A different random sample of 1,000 people yielded the results recorded in table 2. Use this data to answer the questions that follow.

Table 2

people who wear corrective lenses 745
people who wear glasses 618
people who wear contact lenses 127

How many of the 320 million Americans would you predict wear corrective lenses?

238,400,000 is predicted to wear corrective lenses.

Step-by-step explanation:

We can use a ratio table to solve this problem.

So far, with the data given, we can construct a ratio table that looks like this:

Population: 1000, 320,000,000

Cor. Lenses: 745, ?

We know 745 people out of 1000 wear corrective lenses, yet how many out of 320 million people wear them?

To solve this, we need to figure out how many times 1000 is away from 320 million. We can find this out by dividing 320,000,000 by 1000. This results in 320,000. This meant that 1000 was multiplied 320,000 times to get to 320 million. However, what we do to one side of the ratio table, we must do it to the other.

This means we have to multiply 745 by 320,000. This results in 238,400,000. Out of 320 million Americans, 238.4 million wear corrective lenses.
